"I expect to be entertained a long time by this game."
Me too! Initially I found some of the missions too challenging (& a bit corny too, I doubt you'd find IRL a formation with single examples of lots of tanks.), so I copied & edited them, & now I'm having a blast!
I'm especially looking forward to MP (which needs alot of work IMO, although I'll wait for SP issues to be fixed.) & a few other features like ability to set the scroll speed as it zips too fast at times making selecting units without pausing difficult which will be vital for MP (no pausing).
